摘要：

As densities of holographic storage increase, ISI and noise begin to severely limit data fidelity. The problem of ISI can be alleviated through at least two different techniques namely, equalization and low-pass encoding of the data. We study the relative merits of the two methods and quantify their benefit from a density improvement standpoint.
